Patented Mar. 22, 1938 UNITED STATES PATENT OFFICE 4 Claims.

The present application is a continuation in part of 'my copendingapplication Serial No. 65,131, filed Feb. 21, 1936 for water bottle.

The invention relates particularly to the construction at the fillingopening end of a water bottle and to the filling mouth and the closuremeans therefor.

In the drawings,

Fig. 1 is a View of the construction at the filling opening end of awater bottle and embodying the invention.

Fig. 1a. is an edge view of the device of Fig. 1.

Fig. 8 is a view of a modified construction.

Referring to the drawings, 1 represents the body of the water bottlewhich is provided with a filling opening and closure means therefor, thepreferred forms of Which according to the invention are shown in thedrawings and described hereinafter.

The closure for the water bottle in the embodi ments shown in Figs. 1 to3 comprises a band H of rubber or other material which is secured to theflaring walls 12 of the mouth of the bottle above the filling opening byany suitable means such as buttons I3 or the like. Molded integrallywith the band II is a soft rubber plug or stopper I4, through whichpasses a bolt 15 with washers l6 and I1 and wing nut 18 which inoperation squeezes the rubber so that it overflows the walls of thefilling opening and effects a tight closure.

The walls of the filling opening comprise a channel shaped ring member19. The channel member is preferably of the clinch type, the rubber wallof the bottle being molded with a bead construction 20 of a size suchthat when forced into the clincher channel it is held under compression.This avoids any costly assembly of the bottle because of cementing ormoulding operations, the bottle being molded in one part, the stopperand ring member assembled in another part and the tWosnapped together ina leakproof union in the final assembly.

The walls l9a of the filling opening provided by 55 the channel memberare straight in the form shown in Fig. 1, but these may be shaped asshown at 19b in the enlarged view of Fig. 3 to provide an hourglassshape which will be assumed by the rubber plug under compression to forman efiective sealing closure.

The rubber strap or bail I l in the filling operation will swingsideways over the neck of the bottle and completely out of the wayduring the filling stage, while being adapted for use as a bail to hangthe bottle in use as a fountain 0 syringe.

In the embodiment shown in Figs. 4 and 5 the rubber strap or band Hr ismolded integrally with the flaring wall I2 of the mouth of the bottleand is joined therewith only at one end, the other 5 end of the strapterminating in the soft rubber plug or stopper 141' which is molded inone piece with the strap.

In this embodiment of the invention, the stopper is of oblong shape anddesigned to fit and 20 conform to the shape of the channel shaped ringmember 19x which is oblong and provides an oblong filling opening.

As shown in Fig. 5, the strap or band H00 and the stopper 14.1: are somolded integrally with 25 the flaring wall l2 of the bottle mouth, thatif the oblong stopper is applied to the oblong ring member and openingby bending the strap or band straight over without twisting the strap,the oblong shape of the stopper will register with 30 the oblongopening. That is to say, a plane including the axis of the strap or bandand the minor axis of the oblong filling opening also normally passesthrough the minor axis of the oblong stopper, as the parts are molded.The 5 major axes of the oblong filling opening and the oblong stopper,as the parts are molded and without any twisting or sidewise flexing ofthe strap, are therefore normally in parallelism. This enables theoblong stopper to be readily and properly applied to the oblong opening,guided by the strap, by simply avoiding twisting of the strap.

Expressed in another way, the strap normally maintains the central axisof the axis of the stopper in the same plane with the central axis ofthe filling opening, whether the stopper is inserted or not.

The oblong shape of the stopper and filling opening prevent any turningof the cork or stopper as friction is applied and insures its properplacement. The prevention of turning of the stopper as the thumb nut isturned eliminates any tendency of the ring member to turn relative tothe bag body which might result in leakage.

A bolt 1520 is provided, passing through the stopper with washers 16mand Ila: and thumb nut I81: for squeezing the rubber to effect a tightclosure with the ring member I9zc of the filling opening, the walls ofthe ring member being shaped as shown so that the rubber can readilyexpand over the rounded surfaces thereof.

The internally molded bead 20a: is of relatively soft rubber that underpressure is compressed into the channel of the metal ring member, orthroat piece I 9a.. The parts are preferably prepared with a suitablevulcanizing compound whereby the throat piece or ring is held in anhomogeneous relationship to the internal bead and thereby furthersafeguarding the mechanical assembly against any possibility of leakage.

An opening 2| is preferably provided in the strap or band for hangingthe bag when desired.

The stopper construction provided according to one embodiment of thepresent invention employs a rotating threaded means for effectingcompression, but the invention is not limited to this particular meansofeffecting the compression and lateral expansion of the stopper.

As indicated in Fig. 8, cam operated compressing means for the stoppermay be employed, and in the embodiment shown in Fig. 8, the central boltl5y for the stopper My is provided with a closing or operating lever 22at its upper end, the lever 22 having a cam portion 23 to ride on theface of the upper washer lBy and when the lever is moved in onedirection will compress the stopper and be locked in position.

It will be noticed that the soft rubber stopper is longer than the boreof the ring in the direction of the axis, so that when the stopper isdeformed by pressure, its lower portion will assume a flange-likeformation extending under and lying against the flat underside of thering.

I claim:

1. A water bottle or the like having a filling opening and a stopperclosure of soft rubber or similar material, and a strap: or band moldedintegrally in one piece with said stopper and with the wall of thebottle adjacent the filling opening,

said filling opening being non-circular in shape and said stopper beingnon-circular in shape to correspond therewith, said strap normallymaintaining the central axis of said stopper and the central axis ofsaid filling opening in the same plane so that registering of thenon-circular stopper with the non-circular opening is facilitated.

2. A water bottle having a neck provided on its interior with an annularring member, a soft rubber stopper of a length to fit within and extendto a plane below the lower edge of said ring, and means for exerting acompressive force upon the upper and lower faces of said stopper todeform the same where it contacts the annular inner face of the ring,the lower end of said soft rubber being expanded outwardly in the formof a flange extending beyond the bore of said ring and beneath the loweredge thereof and lying against the under, substantially fiat face of thering.

3. A water bottle having a neck provided on its interior with an annularring the bore of which is of generally hour glass shape, a soft rubberstopper, and means for exerting pressure upon said stopper axiallythereof deforming it to fit the substantially upwardly and downwardlyflaring wall of the bore of the ring, said soft rubber stopper being ofsubstantially plain cylindrical form longer than the bore of the annularring to extend to a plane below the lower edge of said ring, forming aflange, when deformed by the pressure, lying against the under face ofthe ring, said flange extending in a plane substantially at right anglesto the axis of the stopper.

4. A water bottle according to claim 1 in which said filling opening isof elongated shape with its longer dimension in the plane of the body ofthe bottle, said. stopper being also of elongated cross sectional shapewith its longer dimension normally maintained by said strap in parallelrelation with the longer dimension of said filling opening.
